304 SS INCH Carbide Drills Inch Speeds and Feeds 304 SS - Milling INCH Warning Always use the speeds and feeds recommended from your tool manufacturer. Easy Speeds And Feeds only serves as a starting point and educational site. 304 SS - HSS Drills INCH Warning Always use the speeds and feeds recommended from your tool manufacturer.

Feeds and speeds formula First is the formula to find the RPM, RPM = SFM* X 3.82 / diameter of the tool (* SFM = Surface Feet per Minute) You can also use the RPM calculator below Calculate RPM Next, the formula for the feedrate uses the RPM from the previous calculation, Feedrate = RPM X Feed per tooth X Number of teeth or

The Speeds and Feeds Calculator uses the following formulas: RPM = (12 * Surface Speed) / (PI * Tool Diameter) [revs/min] Feed Rate = RPM * Chip Load * Number of Teeth (Flutes) [in/min] Where PI is the constant (3.141592654).

The excellent machining properties of these copper-zinc alloys is so well-known that they are often used as benchmarks for descri the machining properties of copper and copper alloys

Turning & Boring: Roughing, approximately .030" deep and .020" per revolution feed. Finishing, .002" to.005" depth of cut and .001" to .002 

If supplement- ed and/or verified by cutting tests conducted under realistic machining conditions, the guideline parameters slightly below that of pure copper, but the presence of the alloying elements means that they can be processed on automatic screw machines or other high-speed machine tools.

Maximum Speeds and Feeds Achieved. For single point turning, cutting speeds up to 4,000 surface feet per minute (SFPM), and feed rates up to 0.015 inches per revolution (IPR) were achieved for practical production periods (>4 hours) on all alloys utilizing a coated carbide insert. The chart below illustrates that the same amount of

Feed rate and cutting depth should be set so that in following passes cutting is done below the previously work hardened layer. For example, in turning, a depth of cut at least 0.015 inch (0.38mm) is recommended if a following operation is planned, and the feed rate should be 0.005 inches (0.13mm) or larger.

The feed speed is the speed at which the cutting tool engages the workpiece. Therefore, you must set the correct feed speed before processing the copper parts, because it will affect the quality, life and surface finish of the copper parts. In addition, copper conducts heat rapidly. Therefore, high feed rates increase tool wear over time.

Speeds are generally 80 to 85% of those used for turning. Heavy sections can be parted in a planer with the aid of a gooseneck finishing tool. Only light cuts 0.005″/stroke to 0.010″/stroke may be taken. Continuous soluble-oil lubrication should be provided. Practice for shaping operations is similar to that for planing. Broaching

Milling Speed and Feed Calculator. Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter
